Research summary
تبحث هذه الدراسة في فعالية الزيت العطري المستخلص من أوراق الخزامى الإنجليزية (Lavandula angustifolia L.) كمبيد حشري ضد يرقات خنفساء الطحين الصدئية (Tribolium castaneum). تم اختبار خمسة تراكيز مختلفة من الزيت العطري (5، 10، 25، 50، 100 ميكرولتر/لتر هواء) على يرقات بعمر 12-14 يوم تحت ظروف مخبرية. تم تسجيل نسب الموت عند فترات زمنية مختلفة (24، 72، 120، 168، 216 ساعة) وتصحيحها وفقًا لقيم الشاهد. أظهرت النتائج زيادة معنوية في نسبة موت اليرقات مع زيادة تركيز الزيت وزمن التعريض، حيث كانت أعلى نسبة موت 60.37% عند التركيز 50 ميكرولتر/لتر هواء بعد 216 ساعة. تشير النتائج إلى إمكانية استخدام الزيت العطري للخزامى الإنجليزية كمبيد حشري بالتبخير لمكافحة خنفساء الطحين الصدئية.
Critical review
دراسة نقدية: تقدم هذه الدراسة نتائج واعدة حول استخدام الزيت العطري للخزامى الإنجليزية كمبيد حشري، إلا أن هناك بعض النقاط التي تحتاج إلى توضيح. أولاً، لم تحقق جميع التراكيز نسبة موت كاملة 100%، مما يشير إلى أن هناك حاجة لمزيد من البحث لتحسين فعالية الزيت. ثانياً، الدراسة تفتقر إلى تحليل شامل لتأثير الزيت على البيئة والأحياء غير المستهدفة، وهو جانب مهم يجب مراعاته في أي استراتيجية مكافحة حيوية. ثالثاً، لم يتم اختبار الزيت في ظروف تخزين حقيقية، مما يثير تساؤلات حول فعاليته في البيئات العملية. أخيراً، يجب دراسة تأثير الزيت على مراحل أخرى من دورة حياة الخنفساء لضمان فعالية شاملة.

This kind of plant is widely spread in Maroq and it used in common

Activity of Ziziphora tenuior L. leaves organic extracts against four pathogenic
bacteria, which were isolated from clinical samples and prepared from Al-Assad hospital
laboratory in Lattakia, were tested by disc diffusion method through 2014.
Res
ults showed that Ziziphora tenuior L. leaves extracts have antibacterial activity
against all Gram positive and negative bacteria. Inhibition zones were recorded between
9mm against Pseudomonas aeruginosa and 44mm against Staphylococcus aureus at
concentration of 200mg/ml for the methanolic extract. Whereas the inhibition zones for the
ethanolic extract were recorded between 7mm at concentration of 40mg/ml against
Streptococcus sp. and 34mm at concentration of 200mg/ml against Staphylococcus aureus.
These results represent the importance of Ziziphora tenuior L. as a source of natural
substances counteraction of pathogenic bacteria.
The antibacterial activity of Inula viscosa L. leaves extracts against some pathogenic bacteria, which were isolated from Al-Assad hospital laboratory in Lattakia, was tested by disc diffusion method.
Results showed that water extracts had antibacte
rial activity against all Gram positive and negative bacteria. The diameters of inhibition zones were between 9 mm against Pseudomonas aeroginosa and 41 mm against Proteus vulgaris.
All Gram positive bacteria showed sensitivity to all organic extracts, so they had antibacterial activity, while Gram negative bacteria showed resistance to chloroform extract except for the one of Klebsiella pneumoniae with an inhibition zone of 12 mm, and resistance for dichlormethan extract except for Pseudomonas aeruginosa with an inhibition zone of 15 mm. there was resistance for diethyl extract except for Serratia marcescens with an inhibition zone of 32 mm.
Ethyl acetate extract had antibacterial activity against all bacteria. Ethanol, methanol and acetone extracts showed antibacterial activity against all bacteria except for Escherichia coli with an inhibition zone of 10 mm.
This study indicated that water and organic Inula viscosa L. leaves extracts had antibacterial activity against pathogenic bacteria which also was tested, especially water extract, ethanol, methanol, ethyl acetate and hexane extracts. So the Inula viscosa L. leaves extracts may be sources for natural antibiotic in future.
This study aims to provide GC-FID and GC-MS analyses of the essential oil of dried aerial parts of Ecballium elaterium L. grown in Jordan and examining its cytotoxicity capacity. Methods: Essential oil was obtained by hydrodistillation using Clevenge
r apparatus. MTT assay method was used to investigate the plant's in vitro antiproliferative activity against MCF-7, Caco-2 and Panc-1 cancer cell lines in addition to normal fibroblast cells. Results: E. elaterium hydrodistilled oil yielded thirty one components, accounting for 76.3% of the total oil content. High contents of nonterpenoidal compounds, sesquiterpenes, and monoterpene characterized the volatile fractions with hinesol (17.2%), the principal compound, benzaldehyde (12.3%) and E-β-ionone (7.8%) as the major constituents. E. elaterium ethanolic extract showed good activity against MCF-7 and Caco-2 cells (IC50 values=29.67 μg/mL and 17.64 μg/mL, respectively). Moreover, all extracts were safe on normal human cells. In conclusion: Evaluation of E. elaterium volatile oil has been conducted for the first time in Jordan; also various extracts were tested for the first time against Panc-1 cells. Furthermore, based on the obtained results, ethanol extract of E. elaterium may be advocated as candidate for breast and colorectal cancers management.
The bio-effect of anise oil and its fruit extracts(alcoholic and
aqueous extract) to control the cowpea beetle, Callosobruchus
maculatus that infest stored leguminous crops was investigated. The
study was conducted according to three treatments: e
vaporation,
direct spray of insects and food spray. The anise oil was used at
different concentrations from 0.05 to 5%. Whereas, the aqueous and
.alcoholic fruit extracts were used as 30%.
